Doc Text:	A flaw was found in goutils where randomly generated alphanumeric strings contain significantly less entropy than expected. Both the `RandomAlphaNumeric` and `CryptoRandomAlphaNumeric` functions always return strings containing at least one digit from 0 to 9. This issue significantly reduces the amount of entropy generated in short strings by these functions.	Story Points:	---

Description Avinash Hanwate 2022-12-28 11:24:56 UTC

Randomly-generated alphanumeric strings contain significantly less entropy than expected. The RandomAlphaNumeric and CryptoRandomAlphaNumeric functions always return strings containing at least one digit from 0 to 9. This significantly reduces the amount of entropy in short strings generated by these functions.
